Coolrun

Today, my coolrun script got accepted at SourceForge. This script enables or disables the powersaving features on the AMD Duron/Athlon/Athlon XP or Sempron line of processors. It does that through direct hardware access to the chipset using the setpci utility. A lot of chipsets are supported at the moment, but unfortunately none of the ATi chipsets are supported because there's no public info available on them.
